3 TRX Configuration

To make use of the FEC, the transmission path needs to use Non-Return-to-Zero (NRZ) coding. In the case of a swapped bit in a data stream using Manchester coding, data reception would be aborted due to a Manchester coding error. At the reception path, telegram settings have to be tight for Wake Check Okay (WCO) and Start of Telegram (SOT) to find the correct SOT. End of Telegram (EOT) has to be weak to get data into the First In First Out (FIFO). The telegram length is the only applicable EOT condition to avoid breaking the reception by the demodulator.
